Breathing mask

ABSTRACT

A breathing mask has a mask body, a mounting bracket and a universal connecting tube. The mask body has a first universal socket bracket having a first spherical recess. The mounting bracket is mounted on the mask body and has a second universal socket bracket having a second spherical recess. The universal connecting tube is mounted universally pivotally in the mask body and has a ball joint mounted universally rotatably in the first and second spherical recesses. The universally rotating ball joint allows a breathing tube connected to the universal connecting tube to pivot to any orientations and prevents the breathing tube from over bending.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a mask, and more particularly to a breathing mask that is connected to a breathing tube and allows the breathing tube to rotate universally such that the breathing tube is able to pivot to a proper orientation preventing itself from over bending and obstructing the air or oxygen conveyance and even pulling the mask to result in leakage no matter what position a patient is located relative to a breathing apparatus.

2. Description of Related Art

A breathing mask is worn on a patient's head and allows the patient to connect to a breathing apparatus and breathe through the breathing apparatus. A conventional breathing mask has a mask body and a headband. The mask body is mounted adjacent to the patient's nose and has two nostril tubes mounted on the mask body and press-contacting and slightly extending into the patient's nostrils. Furthermore, the mask body is able to engage a breathing tube that is connected to a breathing apparatus such that the oxygen is conveyed into the patient's nasal cavity. The headband is attached to the patient's head to ensure that the mask body is fastened securely on the patient's nose.

However, the mask body mounted on the breathing tube by a general mounting manner does not allow the breathing tube to rotate relative to the mask body. When a relative position of the patient to the breathing apparatus is changed, the breathing tube bends in different directions. An excessive bending extent of the breathing tube narrows an internal passage thereof and negatively affects the oxygen conveyance therein. The over bent breathing tube even inadvertently separates from the breathing apparatus or mask body and leads to interrupt the related therapy or endanger the patient's life.

To overcome the shortcomings, the present invention provides a breathing mask to mitigate or obviate the aforementioned problems.

SUMMARY OF THE INVENTION

The main objective of the invention is to provide a breathing mask that is connected to a breathing tube and allows the breathing tube to rotate universally such that the breathing tube is able to pivot to a proper orientation preventing itself from over bending and obstructing the air or oxygen conveyance and even pulling the mask to result in leakage no matter what position a patient is located relative to a breathing apparatus.

A breathing mask in accordance with the present invention has a mask body, a mounting bracket and a universal connecting tube. The mask body has a first universal socket bracket having a first spherical recess. The mounting bracket is mounted on the mask body and has a second universal socket bracket having a second spherical recess. The universal connecting tube is mounted universally pivotally in the mask body and has a ball joint mounted universally rotatably in the first and second spherical recesses. The universally rotating ball joint allows a breathing tube connected to the universal connecting tube to pivot to any orientations and prevents the breathing tube from over bending.

Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

With further reference to FIG. 4, the mask body 10 has a frame 11 and a first universal socket bracket 15.

The frame 11 has two side ends and a through hole 12 defined through the frame 11.

With further reference to FIGS. 5 and 6, the first universal socket bracket 15 is mounted securely in the through hole 12 and has a rear end, a mounting hole 16 and a first spherical recess 17. The mounting hole 16 is defined through the first universal socket bracket 15 and has an inner surface. The first spherical recess 17 is annular and is defined in the inner surface of the mounting hole 16.

With further reference to FIGS. 7 and 8, the mounting bracket 20 is mounted securely on the mask body 10 and has a second universal socket bracket 21 and an assembling member 22.

The second universal socket bracket 21 is hollow and tubular and has a rear end, a fastening hole 26 and a second spherical recess 27. The fastening hole 26 is defined through the second universal socket bracket 21 and has an inner surface. The second spherical recess 27 is annular, is defined in the inner surface of the fastening hole 26 and combines the first spherical recess 17 to form a universal socket.

The assembling member 22 is formed on and protrudes backward from the second universal socket bracket 21.

The universal connecting tube 30 is mounted universally pivotally in the mask body 10 and the mounting bracket 20, protrudes forward from the mask body 10 and has a front end, a rear end, a channel 300 and a ball joint 31. The channel 300 is defined through the universal connecting tube 30. The ball joint 31 is formed on the rear end of the universal connecting tube 30, is mounted universally rotatably in the universal socket formed from the first and second spherical recesses 17, 27 for 360 degrees rotation and has an outer surface 310. The outer surface 310 of the ball joint 31 is spherical so as to smoothly contact and rotate relative to the first and second spherical recesses 17, 27. The ball joint 31 is capable of fluently rotating for 360 degrees due to the limitation made by the first and second spherical recesses 17, 27 instead of being displaced. Furthermore, the universal connecting tube 30 may he made of resilient material such as plastic or rubber such that the universal connecting tube 30 may be press-fitted into or detached from the universal socket from the combined first and second spherical recesses 17, 27 through the front of the mask body 10. Therefore, the universal connecting tube 30 may be quickly attached to or detached from the front of the mask body 10. Alternatively, the aforementioned components are fabricated according to a different step order of assembling the universal connecting tube 30 on the mask body 10 and then combining the mounting bracket 20 to the mask body 10.

The connection bracket 40 is mounted on the assembling member 22 of the mounting bracket 20 opposite to the mask body 10 and may be inserted into a patient's nostrils.

With further reference to FIGS. 9 and 11, the side bands 90 are connected pivotally and respectively to side ends of the frame 11. Each side band 90 is a dual-layer structure and has a fabric layer 91 and a glue layer 92. The glue layer 92 may be a polyester polyurethane layer 92 and is formed on the fabric layer 91 by hot-pressing processes. The fabric layer 91 is soft and makes the user feel comfortable when the side bands are fastened on the user's head. The polyester polyurethane layer 92 has excellent flexibility and supportive strength to allow the side band 90 to intimately fit the patient's face and provide comfort.

The rear band 95 is attached between the side bands 90.

In a preferred embodiment of the present invention, with further reference to FIG. 4, the mask body 10 has multiple buckling members 18 formed on and protruding backward from the rear end of the first universal socket bracket 15. Each buckling member 18 has a buckling hole 180 defined through the buckling member 18. The mounting bracket 20 has multiple hooks 28 and multiple releasing pulls 29. The hooks 28 may be resilient. The hooks 28 are formed on and protrude back from the rear end of the second universal socket bracket 21, correspond to the buckling members 18 and detachably hook respectively in the buckling holes 180 of the buckling members 18. The releasing pulls 29 are U-shaped, formed on the rear end of the second universal socket bracket 21, and correspond to the hooks 28. Each releasing pull 29 has two ends connected to one of the hooks 28 such that the releasing pull 29 and the hook 28 cooperatively form a ring-shaped configuration. Furthermore, each releasing pull 29 extends transversely inward and is inclined backward. Pulling the releasing pulls 29 by fingers disengages the hooks 28 from the buckling holes 180 of the buckling members 18. Therefore, the mounting bracket 20 may be quickly attached to or detached from the mask body 10 for quick assembly and disassembly purposes.

In a preferred embodiment of the present invention, with further reference to FIGS. 3 and 4, the assembling member 22 of the mounting bracket 20 is annular and has a radial flange 221, an axial flange 222 and an annular assembling slot 25. The radial flange 221 is formed on and protrudes radially outward from the second universal socket bracket 21. The axial flange 222 is formed on and protrudes axially backward from the radial flange 221. The annular assembling slot 25 is defined between the axial flange 222 and an outer surface of the second universal socket bracket 21. The connection bracket 40 has a hollow sleeve 41, a hollow body 42 and two hollow nostril insertions 43. The sleeve 41 is mounted detachably in the annular assembling slot 25 of the assembling member 22 and has a rear end. The body 42 is formed on the rear end of the sleeve 41 and communicates with the sleeve 41 and has a rear end. The nostril insertions 43 are formed on the rear end of the body 42 and communicate with the body 42 and each nostril insertion 43 has an air outlet hole defined through the nostril insertion 43.

In a preferred embodiment of the present invention, the mounting bracket 20 has multiple assembling holes 223 defined in the axial flange 222 of the assembling member 22.
